Is this a semen allergy?

I'm seventeen. My boyfriend and I have been sexually active for five months. We always used condoms, and sex was great. We used lube and had tons of foreplay. No complaints. About a month ago, I went on the pill, and suddenly that all changed. The sex itself was better then ever. But after he comes in me, it burns the inside of my vagina like crazy. It only happens when he comes in me....

Out, Out Damn UTI!

Could not cleaning myself a certain way after sex be causing my frequent urinary tract infections? What is the proper way to clean myself after sex (we use condoms and KY)?...

A burning question

I need help! I slept with someone and now I burn and am swollen down there. My family doesn't have insurance and I just turned 18. I heard that there are free women's clinics but I can't find any in houston. Can you help me?...
